<p>PROBLEM TO BE SOLVED: To securely perform the double-lock of a door by providing a control unit, which receives the detection output of a condition switch for detecting door lock of a door lock and unlock mechanism and which operates a dead lock mechanism. SOLUTION: When a signal processing circuit 5 inside of a control circuit 10 receives any one of low pass filter output signal of a first - a fourth low pass filters 2a-2d, the signal processing circuit 5 sends the content data of the door operation and the content data of the dead lock operation by each switch corresponding to each output signal to a request register 63. A drive control circuit 64 selectively supplies the current such as the lock current and the unlock current to a motor 7 or a motor 9 on the basis of the content of the temporary storage of the request register 63 supplied from a memory 63 and the control data inside of a memory corresponding to the content of temporary storage, and controls the operation of the motor 7 or 9. The data having a high priority in order is securely left by the operation of the control device 10 so as to securely carry on the operation having a high priority in order.</p> |
